  • PCAT Question of the Day

The electronegativity of elements increases going from left to right across a row in the periodic table. Which of the following best accompanies this trend in the periodic table?

 

  1. A decrease in ionization energy and an increase in atomic radii
  2. A decrease in atomic radii and a decrease in ionization energy
  3. An increase in ionization energy and a decrease in atomic radii
  4. An increase in ionization energy and an increase in atomic radii
Explanation

This question tests the examinees knowledge of trends within the periodic table. In general, as you move from left to right across a row in the periodic table, electronegativity and ionization energy increases while atomic radii decrease. Therefore, C is the correct answer.
